Because only those target cells have receptors for that particular hormone. Some hormones bind to receptors on the surface of target cells. Others enter the cells and bind to receptors in the cytoplasm or nucleus. Why do hormones only target specific cells? A target cell responds to a hormone because it bears receptors for the hormone .
However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone,.
You might be wondering “What makes a cell a target cell for hormones?”
In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone. Reception of a radio broadcast provides a good analogy.
Which target cell will respond to hormone #1?
A target cell responds to a hormone because it bears receptorsfor the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
How do hormone receptors affect cells?
Hormones can affect cells directly through intracellular hormone receptors or indirectly through plasma membrane hormone receptors. Question is, how do hormones enter cells?
You could be wondering “Do all cells in the body respond to hormones?”
Well, most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone.
How do hormone receptors work?
Hormone receptors are found either exposed on the surface of the cell or within the cell, depending on the type of hormone. In very basic terms, binding of hormone to receptor triggers a cascade of reactions within the cell that affects function .
Then, how do hormones work?
Receptors for a specific hormone may be found on many different cells or may be limited to a small number of specialized cells. For example, thyroid hormones act on many different tissue types, stimulating metabolic activity throughout the body . Cells can have many receptors for the same hormone,.
Hormones are chemical messengers secreted into blood or extracellular fluid by one cell that affect the functioning of other cells. A target cell responds to a hormone because it bears receptors for the hormone.
What are targettarget cells?
Target cells are medically called codocytes .
Target cell’s mechanism of formation Codocytes or popularly known as target cells are formed if the red blood cell’s surface is increased disproportionately to its volume. Target cells are actually red blood cells, which are extremely thin and have an excessive cell membrane.
What are target cells/codocytes?
Image 1: The slide contains a microscopic view of target cells/codocytes. Codocytes or popularly known as target cells are formed if the red blood cell’s surface is increased disproportionately to its volume. Target cells are actually red blood cells , which are extremely thin and have an excessive cell membrane.
